shortages and accelerating climate change, direct seeded rice (DSR) has emerged as a feasible and resource-efficient alternative to conventional transplanted puddled rice (TPR) systems, conserving water and reducing methane emissions. However, the initial growth phases are frequently impeded by inadequate seedling emergence, intensive weed competition, nutritional deficiencies and exposure to variable soil moisture and aeration conditions in some DSR systems, including low nitrogen use efficiency, which can impair the establishment of a healthy crop stand and stability of its yield under DSR. Identifying and phenotyping rice germplasm for critical physiological traits is essential for developing cultivars that thrive in DSR environments. The physiological basis of genotypes adaption to DSR conditions need to be integrated with phenotyping and breeding strategies. This review synthesizes the knowledge of the physiological traits that facilitate DSR adaptation evaluates both conventional and high-throughput phenotyping (HTP) techniques — digital imaging, canopy temperature measurement, chlorophyll fluorescence analysis, and remote sensing technologies to precisely evaluate these traits in field and controlled environment and examines how quantitative trait loci (QTL) mapping, genome-wide association studies (GWAS), and marker-assisted selection (MAS), significantly facilitates the development of rice varieties suitable for DSR. The review highlights the importance of multi-trait phenotyping frameworks and multi-environment testing in accelerating genetic improvement and ensuring sustainable rice production in direct seeded agricultural systems.","由于水资源不足、劳动力短缺以及气候变化加剧，直播稻（direct seeded rice, DSR）已成为传统移栽水田稻（transplanted puddled rice, TPR）体系的一种可行且资源高效的替代方案，能够节约用水并减少甲烷排放。然而，在一些直播稻体系中，初期生长阶段常常受到出苗不齐、杂草竞争激烈、营养缺乏以及土壤水分和通气条件多变等因素的制约，包括氮利用效率低，这些问题可能损害健康作物群体的建成及其在直播稻条件下产量的稳定性。鉴定和表型分析水稻种质的关键生理性状，对于培育在直播稻环境中生长良好的品种至关重要。基因型适应直播稻条件的生理基础需要与表型分析和育种策略相结合。本综述综合了促进直播稻适应的生理性状相关知识，评估了传统和高通量表型分析（high-throughput phenotyping, HTP）技术——数字成像、冠层温度测量、叶绿素荧光分析和遥感技术——在田间和受控环境中精确评价这些性状的作用，并探讨了数量性状位点（quantitative trait loci, QTL）定位、全基因组关联分析（genome-wide association studies, GWAS）和标记辅助选择（marker-assisted selection, MAS）如何显著促进适宜直播稻的水稻品种选育。本综述强调了多性状表型分析框架和多环境测试在加速遗传改良、确保直播稻农业生产体系可持续水稻生产方面的重要性。","Genetics and Molecular Research","论文",77,{"impact":126,"substance":212,"depth":213,"authority":17,"freshness":214,"relevant":20,"comment":215},20,17,9,"系统综述直播稻生理适应、表型技术与分子育种进展，对水稻轻简化栽培与智慧育种有参考价值，但属综述类论文，影响偏行业细分。",[217],{"name":208,"url":205},[25,26,219,220,221],"智慧育种","表型组学","直播稻",{"code":31,"slug":32,"name":25,"path":33,"parent_code":34},[],{"status":37,"locked":13,"version":38,"method":39,"evidence":225},{"candidates":226,"agricultural_evidence":44},[227,232,239,246,253,258,264],{"code":31,"score":228,"supported":44,"title":229,"abstract":230,"tags":231},15,[32],[25,32],[25],{"code":233,"score":68,"supported":44,"title":234,"abstract":235,"tags":238},"H2",[],[236,237],"土壤","soil",[],{"code":240,"score":68,"supported":44,"title":241,"abstract":242,"tags":245},"H7",[],[243,244],"气候变化","climate change",[],{"code":247,"score":68,"supported":44,"title":248,"abstract":249,"tags":252},"I3",[],[250,251],"遥感","remote sensing",[],{"code":58,"score":19,"supported":44,"title":254,"abstract":255,"tags":257},[],[256],"germplasm",[26],{"code":259,"score":52,"supported":44,"title":260,"abstract":261,"tags":263},"H3",[],[262],"水资源",[],{"code":265,"score":20,"supported":13,"title":266,"abstract":267,"tags":268},"F2",[],[],[219],[270,271],"直播稻 生理适应 遗传改良","水稻 高通量表型 分子标记","直播稻生理适应遗传改良-5161","10.4238\u002Fvknnq971",{"doi":273,"openalex_id":275,"authors":276,"venue":208,"cited_by_count":157,"oa_url":205,"card":288,"direction":292,"ingested_from":294},"W7222406581",[277,279,282,284,286],{"name":278,"orcid":8},"Vaishnavi.
